Chapter 168

As they continued to advance into the depths of the cave, the scene inside slowly unfolded before the three, and the mood of these three was becoming more and more excited!

This was simply too incredible. As they continued to go deeper, it appeared more and more different from an ordinary cave! If one had to describe it, it was more like a secret base of grand scale hidden deep underground!

Still remember when they first stepped into this mysterious cave, they found some of the same symbols on the stone wall that Gu Changzheng had encountered in Zizhen before. However, after continuing to move inside, these symbols disappeared without a trace as if they had evaporated from the world.

At this moment, the layout inside the cave gradually became clear before everyone's eyes. The entire cave presented a perfect arched circle, with a height of about four meters and a width of about three meters. What was remarkable was that a thick line extended straight from the ground to the top, and at its end, a pitch-black cylindrical object was actually hanging.

Gu Changzheng hurriedly summoned the other two companions and gathered the three burning torches together. In an instant, the fire soared into the sky, and the originally dim top of the cave was instantly illuminated as if it were daytime. At this moment, the three people almost exclaimed at the same time! Because they were surprised to find that this was indeed a defensive fortification built by human hands. After careful identification, the hanging object was found to be a ventilation fan, and the thick line was likely a wire conduit made of some special material.

Looking at it this way, this place was very likely once an air-raid shelter used to resist air raids!

The three looked at each other, and Peng Weibing was the first to speak: "I haven't heard of such an air-raid fortification. If there was one, there would definitely be a record!"

Gu Changzheng also expected that this place would not have been built by the local government. Combined with the geographical location here, he guessed that this air-raid shelter was very likely a historical legacy.

He looked carefully at the surrounding ground and walls. Unlike the natural cave above, it was relatively dry here. At this time, the flames of the torches in the hands of the three suddenly fell backward. "Quick, extinguish the torches!" Gu Changzheng whispered and shouted!

Before the other two could react, they hurriedly thrust the burning torches toward the damp places on the ground. After only a moment, the burning torches gradually extinguished, and the surroundings instantly fell into pitch-black darkness.

Luo Fei's heart tightened, and he hurriedly lowered his voice and asked: "Captain Gu, what is going on?" Gu Changzheng also didn't dare to speak loudly. He lowered his voice to the extreme and responded: "I feel like there are other people here!" After saying this, the three people unconsciously clenched the extinguished torches in their hands, then held their breath and stood still in place, not daring to move at all.

After being in a stalemate for a while, a faint, extremely subtle sound suddenly came from afar. Listening carefully, the sound was as if someone was crying sadly. Although they were in pitch-black darkness, relying on their previous observation and memory of the surrounding environment, the three of them could still feel the gaze passed between each other. Because they had already seen the situation here clearly not long ago, even if there was no light to illuminate it, they still cautiously continued to move forward in the dark.

As they continued to go deeper, those originally faint and hard-to-distinguish crying sounds became clearer and clearer. After walking another hundred meters or so, the crying sound was almost as if it were close at hand, clearly audible! By this time, the three people almost simultaneously slowed down their steps with a tacit understanding, and then moved forward slowly like snails crawling.

The three walked along the wall. At this time, they felt that the tunnel was clearly leaning to the right. It seemed that this passage had reached a bend. Sure enough, after groping for a few more meters, the bend became more obvious, and then a glimmer of light appeared in front! And those crying sounds were clearly transmitted from this place!

Gu Changzheng patted Luo Fei lightly to signal him to stay, and touched Peng Weibing's arm, whispering: "Director Peng, shall we two go up and take a look?"

Peng Weibing lowered his throat and made a strange sound: "Let's go!" After speaking, he was about to set off.

"Wait a minute!" Gu Changzheng whispered: "I'm in front, you're in the back. We two are more than ten steps apart. Pay attention to observing the surroundings. There might be some secret doors or something here!"

Peng Weibing nodded, but suddenly remembered that it was too dark here, and he couldn't see the other party nodding, so he still used a low and hoarse strange voice: "Okay!" Although Gu Changzheng couldn't see his appearance, he was also amused by his strange voice and wanted to laugh. He held back and didn't laugh out loud, taking the first step, hunching his waist, and slowly groping toward the light.

This Peng Weibing was very cooperative. Calculating Gu Changzheng's steps in his heart, he also hunched his waist and rushed out!

At this time, Gu Changzheng was not far from the light, and the situation in front could be seen relatively clearly. The light came from an arched wooden door, and there seemed to be another world inside.

He cautiously looked around and didn't find any secret sentries or anything. Thinking that this place was so hidden, it really didn't need to engage in those things.

Seeing that there were no safety hazards around, he quickly ran to the wooden door and pushed it lightly with his hand. The door was not bolted!

Gu Changzheng's back hair stood up instantly! A dangerous aura struck! He immediately knew that someone must have come out of the door!

At this moment, he heard a dull sound and a muffled groan behind him! He turned his head rapidly, only to see a black shadow in the dark dragging a person toward the corner of the wall with both hands! It was exactly Peng Donkey who had come over behind him!

Seeing Peng Donkey put the person in the corner and run over quickly, he still used his strange voice: "Captain Gu, you're really something! How did you know they had an ambush?" Gu Changzheng smiled and didn't answer, thinking in his heart that I didn't know, it was nothing more than being cautious!

He pointed to the inside of the door, signaling with his hand to follow the tactics just now, and the two opened the distance to cover each other. Peng Donkey hurriedly nodded. Gu Changzheng patted him, slowly pushed the door completely open, and flashed in.

It was not just a passage like the outside. It was brightly lit inside, and it looked not small in area. The first thing that caught their eyes was a small pavilion-like building, just like the property guard booth at the entrance of a common residential area outside. At this time, the door of the pavilion was wide open, and there was no one inside. It seemed that it was the person just dealt with by Peng Donkey.

Behind the guard booth was an iron door, and the crying sound came from behind the iron door!
